Therefore, a shape change of the figure serving as a result of manufacturing techniques and/or tolerances may be expected. Therefore, the embodiment of the disclosure should not be construed as limited to a particular shape of a region as shown herein, but includes a shape deviation caused by manufacturing tolerance. For example, a shown or described flat area may generally have rough and/or non-linear features. Moreover, a shown acute angle may be round. Therefore, a region shown in the figure is essentially schematic, and a shape thereof is not intended to show an accurate shape of the region, and is not intended to limit a range of the claims of the disclosure.

FIG. 1 is a top view of a display panel according to an embodiment of the disclosure. Referring to FIG. 1, a display panel 100 in the embodiment of the disclosure includes a display region AR and a non-display region NR, wherein the non-display region NR is disposed at one side of the display region AR, or the non-display region NR surrounds the display region AR. In other words, the non-display region NR is disposed at one lateral side of the display region AR but it is adjusted depending on different needs. Take that the non-display region NR surrounds the display region AR for example: when being applied to rectangular display region, the non-display region NR is located at one lateral side, two lateral sides, three lateral sides or four lateral sides of the display region AR; when being applied to non-rectangular display region or circular display region, the non-display region NR is located in adjacency to the display region AR, which forms that the non-display region NR is located on a partial periphery or the overall periphery of the display region AR. Generally speaking, the gate driver circuit is typically fabricated in the non-display region of the panel, border area. However, in the embodiment of the disclosure, the gate driver circuit is disposed in the display region AR. The following embodiment describes how the gate driver circuit is disposed in the display region AR.

For instance, the display panel 100 in the embodiment includes a pixel array disposed in the display region AR. The pixel array is arranged in three different aspects as illustrated in FIG. 2A to FIG. 2C, for example.

FIG. 2A is a schematic view showing arrangement of a pixel array according to an embodiment of the disclosure. As shown in FIG. 2A, a pixel array 101 is disposed in the display region AR of FIG. 1, and the pixel array 101 is composed of a plurality of pixel units (PX1, PX2, PX3, PX4) arranged repeatedly. FIG. 2A is exemplified with four groups of pixel units, namely pixel unit PX1, pixel unit PX2, pixel unit PX3 and pixel unit PX4 arranged repeatedly. However, it should be indicated that the display panel 100 actually includes more pixel units arranged repeatedly. The pixel unit PX2, the pixel unit PX 3 and the pixel unit PX4 are configured in the same manner as the pixel unit PX1. Therefore, only the pixel unit PX1 is described for exemplary purpose.

Referring to the embodiment of FIG. 2A, the pixel array 101 includes a plurality of gate lines (GL1, GL2, GL3 . . . ) disposed in the display region AR and a plurality of data lines (DL1, DL2 . . . ) disposed in the display region AR. Each of the pixel units (PX1, PX2, PX3, PX4) includes three gate lines (GL1, GL2, GL3), two data lines (DL1, DL2) and six sub-pixels (102A, 102B, 102C, 102D, 102E, 102F) and each of the sub-pixels is electrically connected to one of the gate lines and one of the data lines in the pixel array 101 respectively. In the embodiment, the gate lines (GL1, GL2, GL3 . . . ) and the data lines (DL1, DL2 . . . ) are arranged in an interlacing manner, and an insulating layer is sandwiched between the gate lines (GL1, GL2, GL3 . . . ) and the data lines (DL1, DL2 . . . ). In other words, the extending direction of the gate lines (GL1, GL2, GL3 . . . ) and the extending direction of the data lines (DL1, DL2 . . . ) are not parallel with each other. In the embodiment of FIG. 2A, the extending direction of the gate lines (GL1, GL2, GL3 . . . ) is substantially perpendicular to the extending direction of the data lines (DL1, DL2 . . . ), which should not be construed as a limitation to the disclosure. For the purpose of conductivity, the gate lines (GL1, GL2, GL3 . . . ) and the data lines (DL1, DL2 . . . ) are formed of metal material in most cases, but the disclosure provides no limitation thereto. According to other embodiments, the gate lines (GL1, GL2, GL3 . . . ) and the data lines (DL1, DL2 . . . ) are formed of other conductive material such as alloy, nitride of metal material, oxide of metal material, oxynitride of metal material or other suitable material, or a stacked layer of metal material and other conductive material.

Specifically, as shown in FIG. 2A, the three gate lines of the pixel unit PX1 include a first gate line GL1, a second gate line GL2 and a third gate line GL3. The two data lines of the pixel unit PX1 include a first data line DL1 and a second data line DL2. The six sub-pixels of the pixel unit PX1 include a first sub-pixel 102A, a second sub-pixel 102B, a third sub-pixel 102C, a fourth sub-pixel 102D, a fifth sub-pixel 102E and a sixth sub-pixel 102F. In the pixel unit PX1, the first sub-pixel 102A is electrically connected to the first gate line GL1 and the first data line DL1 respectively through a switch element A1, the second sub-pixel 102B is electrically connected to the first gate line GL1 and the second data line DL2 respectively through a switch element A2, the third sub-pixel 102C is electrically connected to the second gate line GL2 and the first data line DL1 of another pixel unit PX2 adjacent to the pixel unit PX1 respectively through a switch element A3. In the embodiment, the pixel unit that is “adjacent to” the pixel unit PX1 refers to another pixel unit that is the closest to the pixel unit PX1, and for example, refers to the next pixel unit arranged continuously along the extending direction of the gate line.

Additionally, in FIG. 2A, the fourth sub-pixel 102D is electrically connected to the second gate line GL2 and the second data line DL2 respectively through a switch element A4, the fifth sub-pixel 102E is electrically connected to the third gate line GL3 and the second data line DL2 respectively through a switch element A5, the sixth sub-pixel 102F is electrically connected to the third gate line GL3 and the first data line DL1 of another pixel unit PX2 respectively through a switch element A6. In the embodiment, the first sub-pixel 102A, the second sub-pixel 102B and the third sub-pixel 102C are disposed between the first gate line GL1 and the second gate line GL2, and the fourth sub-pixel 102D, the fifth sub-pixel 102E, and the sixth sub-pixel 102F are disposed between the second gate line GL2 and the third gate line GL3.

Referring to FIG. 2A, the gate driver circuit is disposed in the pixel array 101 of the display region AR, and the gate driver circuit includes a plurality of driving units 200, and each of the plurality of driving units 200 includes a plurality of active elements TFT and a plurality of signal lines SL. In the embodiment of FIG. 2A, since each of the pixel units (PX1, PX2, PX3, PX4) is only provided with two data lines (DL1, DL2), and the third data line is omitted. In comparison of the conventional display panel includes three data lines in the pixel unit, in this manner, there are more space available, so that the driving unit 200 can be correspondingly disposed between the region formed by adjacent sub-pixels or pixel units. More specifically, the driving units 200 are disposed in a space between the second sub-pixel 102B and the third sub-pixel 102C, and disposed in a space between the fifth sub-pixel 102E and the sixth sub-pixel 102F. Furthermore, one of the signal lines SL of the driving unit 200 is disposed between the second sub-pixel 102B and the third sub-pixel 102C of the pixel unit PX1, and one of the signal lines SL is substantially parallel with the data lines (DL1, DL2). In the embodiment of FIG. 2A, each of the sub-pixels is arranged in rectangular shape and the data lines (DL1, DL2) are substantially perpendicular to the gate line (GL1, GL2, GL3). In this manner, the signal line SL is substantially parallel with the data lines (DL1, DL2), which should not be construed as a limitation to the disclosure. In other embodiments, the sub-pixels are arranged in non-rectangular shape. Therefore, the signal line SL is not completely parallel with the data lines (DL1, DL2). With the configuration shown in FIG. 2A, it is possible to effectively dispose the gate driver circuit in the pixel array 101 of the display region AR, thereby achieving the technical effect of reducing cost, significantly decreasing border area and increasing the area of display region.

FIG. 2B is a schematic view showing arrangement of a pixel array according to another embodiment of the disclosure. FIG. 2B is similar to the pixel array 101 in FIG. 2A, therefore, the same elements are represented by the same numerals and no repetition is incorporated herein. The difference between the embodiments of FIG. 2B and FIG. 2A is that each of the sub-pixels is connected in different manners.

The pixel unit PX2, the pixel unit PX3 and the pixel unit PX4 are disposed in the same manner as the pixel unit PX1; therefore, no repetition is incorporated herein and labeling is omitted.

Likewise, in the embodiment of FIG. 2B, the gate driver circuit is disposed in the pixel array 101 of the display region AR. Since each of the pixel units (PX1, PX2, PX3, PX4) is only provided with two data lines (DL1, DL2), and the third data line is omitted. In comparison with the conventional display panel includes three data lines and three gate lines in the pixel unit, there are more available space between the region formed by adjacent sub-pixels or pixel units (102B and 102C; 102E and 102F) in the embodiment, so that the driving units 200 can be correspondingly disposed between the region formed by adjacent sub-pixels or pixel units (102B and 102C; 102E and 102F). With the configuration shown in FIG. 2B, it is possible to effectively dispose the gate driver circuit in the pixel array 101 of the display region AR, thereby achieving the technical effect of reducing cost, significantly decreasing border area and increasing the area of display region.

FIG. 2C is a schematic view showing arrangement of a pixel array according to yet another embodiment of the disclosure. FIG. 2C is similar to the pixel array 101 in FIG. 2A; therefore, the same elements are represented by the same numerals and no repetition is incorporated herein. The difference between the embodiments of FIG. 2C and FIG. 2A is that each of the sub-pixels is connected in different manners. As shown in FIG. 2C, in the pixel unit PX1, the first sub-pixel 102A is electrically connected to the first gate line GL1 and the second data line DL2 receptively through the switch clement A1, the second sub-pixel 102B is electrically connected to the second gate line GL2 and the second data line DL2 respectively through the switch element A2, the third sub-pixel 102C is electrically connected to the first gate line GL1 and the first data line DL1 of another pixel unit PX2 adjacent to the pixel unit PX1 respectively through the switch element A3.

Likewise, in the embodiment of FIG. 2C, the gate driver circuit is disposed in the pixel array 101 of the display region AR. Since each of the pixel units (PX1, PX2, PX3, PX4) is only provided with two data lines (DL1, DL2), and the third data line is omitted. In comparison with the conventional display panel, there are more available space between the region formed by adjacent sub-pixels or pixel units (102B and 102C; 102E and 102F) in the embodiment, so that the driving units 200 can be correspondingly disposed between the region formed by adjacent pixel units (102B and 102C; 102E and 102F). With the configuration shown in FIG. 2C, it is possible to effectively dispose the gate driver circuit in the pixel array 101 of the display region AR, thereby achieving the technical effect of reducing cost, significantly decreasing border area and increasing the area of display region.

In the embodiments of FIG. 2A to FIG. 2C, it is only exemplified that the gate driver circuit includes the plurality of driving units 200, and each of the driving units 200 includes the plurality of active elements TFT and the plurality of signal lines SL, but the connection/configuration method of the active elements TFT and the signal lines SL are not described in details. The following embodiment describes different aspects of realization of the driving units 200.

FIG. 3 is a circuit diagram of a driving unit according to an embodiment of the disclosure. In the embodiment, the gate driver circuit in the pixel array 101 in FIG. 2A to FIG. 2C is composed of the plurality of driving units 200 shown in FIG. 3. Specifically, the gate driver circuit is formed as multi-stage driving unit with a plurality of driving units 200 connected in series, and each stage of driving units outputs to the corresponding gate line. For example, a first-stage driving unit outputs to a first gate line, a second-stage driving unit outputs to a second gate line, forming relative relationship in order. That is, the output of the first-stage driving unit electrically connects with the first gate line, and the output of the second-stage driving unit electrically connects with the second gate line. For ease of describing, N-stage is used in the following paragraphs for description; that is, the N-stage driving unit outputs to the Nth gate line, that is, the output of the N-stage driving unit electrically connects with the Nth gate line, wherein N is a positive integer. In the embodiment, the signal lines SL in FIG. 2A to FIG. 2C, for example, include a power signal line VSS, a clock signal line CK, a pre-stage input line IN1, a post-stage input line IN2 and an output line OP.

For example, if the pre-stage input line IN1 is electrically connected the first gate line, the output line OP is electrically connected to the second gate line, and the post-stage input line IN2 is electrically connected to the third gate line. Based on the electrical connection method shown in FIG. 3, the driving unit 200 is disposed in the pixel array 101 in two manners as shown in FIG. 4A and FIG. 4B.

FIG. 4A is a schematic view showing a configuration method of a driving unit according the embodiment of FIG. 3. In the embodiment of FIG. 4A, the plurality of driving units 200 are composed of a first driving unit 200A, a second driving unit 200B and a third driving unit 200C arranged repeatedly. In other words, the gate driver circuit has a plurality of first driving units 200A, the second driving units 200B and the third driving units 200C arranged in order repeatedly. As shown in FIG. 4A, the pre-stage input line IN1, the post-stage input line IN2 and the output line OP of each of the driving units (200A, 200B, 200C) are respectively connected three of the gate lines in the display region AR, and at least one of the sub-pixels 102 is disposed between the clock signal line CK and one of the data lines DL. Additionally, the connection method of each of the driving units (200A, 200B, 200C) is configured in the manner as shown in the embodiment of FIG. 3.

Specifically, in the embodiment of FIG. 4A, the gate line includes (N−1)th gate line G(n−1), Nth gate line G(n), (N+1)th gate line G(n+1), (N+2)th gate line G(n+2) and (N+3)th gate line G(n+3), wherein N is an integer larger than 1. As shown in FIG. 4A, in the first driving unit 200A, the pre-stage input line IN1 is connected to the (N−1)th gate line G(n−1), the post-stage input line IN2 is connected to (N+1)th gate line G(n+1), and the output line OP is connected to the Nth gate line G(n). In the second driving unit 200B, the pre-stage input line IN1 is connected to the Nth gate line G(n), the post-stage input line IN2 is connected to the (N+2)th gate line G(n+2), and the output line OP is connected to the (N+1)th gate line G(n+1).

In the embodiment, the configuration on the “same horizontal line” refers to that the first active element T1, the second active element T2, the third active element T3 and the fourth active element T4 of all the driving units are disposed in a space between two adjacent rows of sub-pixels 102 at both sides of the extending direction of one of the gate lines. Take the (N+1)th gate line G(n+1) in FIG. 4A as an example, the horizontal line LN1 is located in a space between two rows of sub-pixels 102 at both sides of the (N+1)th gate line G(n+1), and the space thereof is extended along the extending direction of the (N+1)th gate line G(n+1). In this manner, in the embodiment, the first active element T1, the second active element T2, the third active element T3, and the fourth active element T4 of the driving units are disposed in the same space. In particular, in FIG. 4A, the four active elements (T1-T4) in the first driving unit 200A, the second driving unit 200B and the third driving unit 200C on the horizontal line LN1 are respectively arranged in a regular order, and the arranging order is the third active element T3, the first active element T1, the second active element T2 and the fourth active element T4. In the embodiment of the disclosure, “regular arranging order” refers to that, in each of the driving units (200A, 200B, 200C), all of the active elements are arranged in the order of the third active element T3, the first active element T1, the second active element T2 and the fourth active element T4 from left to right. In this manner, with the configuration shown in FIG. 4A, it is possible to effectively dispose the driving units 200 including four active elements in the pixel array 101 of the display region AR.

In the embodiments of FIG. 4B and FIG. 4A, the plurality of the driving units 200 are also composed of the first driving unit 200A, the second driving unit 200B and the third driving unit 200C arranged repeatedly. The difference between FIG. 4B and FIG. 4A lies in the layout of signal lines and configuration method of active elements. However, in FIG. 4B, the connection method of the driving units (200A, 200B, 200C) still corresponds to the embodiment of FIG. 3.

As shown in FIG. 4B, the second active element T2 and the fourth active element T4 of the first driving unit 200A are connected to the Nth gate line G(n) through the first active element T1 of the second driving unit 200B.

In the second driving unit DR2 of FIG. 8, the arrangement from right to left includes the first active element M1 (and/or first capacitor C1), the fourth active element M4 (and/or the second active element M2, the third active element M3), the seventh active element M7 (and/or the second capacitor C2), the sixth active element M6 and the fifth active element M5. Specifically, the left side of FIG. 8 is, for example, defined as one side close to the first data line D1, and the right side is, for example, defined as one side close to the twenty-fifth data line D25. In this manner, the relative configuration position of each of the elements of the first driving unit DR1 is mirror symmetrical to the relative configuration position of each of the elements of the second driving unit DR2.

Referring to FIG. 9, the signal line 100A and the signal line 100B for the first driving unit DR1 and the second driving unit DR2 are disposed between two adjacent sub-pixels SPX. In the meantime, referring to FIG. 7A or FIG. 7B, in the pixel array 10, there is no data line or gate line provided between a portion of two adjacent columns or two adjacent rows of sub-pixels. Therefore, the embodiment describes that the first driving unit DR1 and the second driving unit DR2 are disposed in the space thereof (the space in which no data line or gate line is provided), and the plurality of the driving units DR are disposed in the display region AR to achieve the effect of narrow border area. In the embodiment, the first active element M1, the fourth active element M4, the fifth active element M5 and the seventh active element M7 of the first driving unit DR1 are disposed on the same horizontal line LN1 along the extending direction E2 of the gate line, and the second active element M2, the third active element M3 and the sixth active element M6 are disposed on another identical horizontal line LN2 along the extending direction E2 of the gate line.

For example, the configuration of “on the same horizontal line” refers to that at least a portion of the active elements of the driving unit is disposed in a space between two adjacent gate lines. Take the first active element M1, the fourth active element M4, the fifth active element M5 and the seventh active element M7 of the driving unit DR1 in FIG. 9 as an example, the first active element M1, the fourth active element M4, the fifth active element M5 and the seventh active element M7 of the first driving unit DR1 are disposed in the space between the fourth gate line G4 and the fifth gate line G5, and the space thereof is extended along the extending direction E2 of the gate line.

The above-mentioned same space refers to a space between two adjacent gate lines, which is also described as being disposed on “the same horizontal line.”

Although the configuration “on the same horizontal line” described above is exemplified with the configuration in the space between two adjacent gate lines, the disclosure provides no limitation thereto. In some embodiments, the configuration on “the same horizontal line” is exemplified with the configuration between two adjacent rows of sub-pixels SPX. Take FIG. 9 as an example, “the configuration on the same horizontal line LN1” represents the configuration between the fifth row of sub-pixel SPX and the sixth sub-pixel SPX counted from the top.

In some embodiments, the shorter the signal line that is electrically connected to the signal node Q and the signal node P, a better quality of the display panel is achieved. In the embodiment, the first capacitor C1 is adjacent to the first active element M1, for example, located between four identical pixel units PX that are adjacent to each other, and the second active element M2 is adjacent to the third active element M3, for example, located between four identical pixel units PX that are adjacent to each other. In this manner, the signal line that is electrically connected to the signal node Q and the signal node P can be shorter.

In the embodiment of FIG. 9, the clock signal is grouped in the number of eight, the first clock signal 120 of the first driving unit DR1 is electrically connected to a third-stage (n=3) clock signal HC3, and the first driving unit DR1 generates the driving signal of the third-stage gate line (third gate line G3), and n=3, for example, please also refer to the circuit diagram of FIG. 8. When the first driving unit DR1 generates the driving signal (i.e., n=3) of the third-stage gate line (third gate line G3), the output line 160 thereof is electrically connected to the third-stage gate line (third gate line G3), the pre-stage input line 140 is electrically connected to the first-stage gate line (first gate line G1), the post-stage input line 150 is electrically connected to the seventh-stage gate line (seventh gate line G7), the first clock signal line 120 is electrically connected to a third-stage clock signal HC3 and the second clock signal line 130 is electrically connected to a seventh-stage clock signal HC7. The rest is deduced from the above. When the second driving unit DR2 generates the driving signal (i.e., n=7) of the seventh-stage gate line (seventh gate line G7), the output line 160 thereof is electrically connected to the seventh-stage gate line (seventh gate line G7), the pre-stage input line 140 is electrically connected to the fifth-stage gate line (fifth gate line G5), the post-stage input line 150 is electrically connected to the eleventh-stage gate line (eleventh gate line G11), the first clock signal line 120 is electrically connected to the seventh-stage clock signal HC7 and the second clock signal line 130 is electrically connected to an eleventh-stage clock signal HC11 (i.e., HC3).
